Why is the photosynthesis system of C4 plants more beneficial than the photosynthesis system of C3 plants?
The C4 photosynthetic system was evolved to maximizing the availability of carbon dioxide whereas to minimizing the loss of water. C4 plants are two times more efficient as compared to C3 varieties based on the process of carbon fixation. In C4 plants, to fix one gram of CO2 molecule it loses only 300 g of water by the process of evaporation while the C3 plants lose 600 g of water for the same grams of carbon dioxide to get fixed.
